    BACKGROUND OF THE INVENTION The invention relates to an arrangement and method related to the mixing and handling of by-product materials.
    The subject matter of the invention is described in more detail in the preambles of the independent claims of the application.
    The industry generates large amounts of industrial by-products such as ash, slag and fines. Often these materials are difficult to utilize due to the ingredients they contain. In addition, the handling of these side-stream materials has been found to be cumbersome. Thus, the utilization of side-stream materials is difficult and they even have to be disposed of as waste heaps. Waste causes significant costs and environmental risks for production plants.
    BRIEF DESCRIPTION OF THE INVENTION The idea of the invention is to provide a new and improved arrangement and method for mixing and handling industrial by-product materials.
    The characteristic features of the arrangement according to the invention are presented in the characterizing part of the independent device claim.
    The characteristic features of the method according to the invention are set out in the characterizing part of the independent method claim. N The idea of the presented solution is that at least = one industrial side stream material is mixed by means of a mixer connected to the mobile machine. The solution thus utilizes a mobile mixer. > 30 One of the advantages of the presented solution is that the mixer unit formed by the machine and the mixer is small in investment and very functionally flexible. The solution is easy to scale by increasing the number of units. In addition, the solution is very simple and does not require massive
    all hardware. Due to the proposed solution, it is not necessary to build any new fixed infrastructure at the factory landfill or similar workstation.
    A further advantage of the proposed new method is that the by-product materials which are difficult to handle can be processed in a factory landfill in a form in which they can be transported to the place of use by normal means of transport in an efficient and safe manner. In the method, the pulp can be made into a ready-to-cast pulp charge in a mixer at once.
    The presented solution is suitable for industrial scale manufacturing and processing and the end product can be an industrial product. The solution can be used to make geopolymers from industrial side streams even as side streams are generated.
    It should be noted that in this application, a geopolymer may also mean an alkali-activated material. In the light of current knowledge, geopolymer and alkali-activating material mean the same material. In such a material, silica is SiO; and alumina Al, O 3 have reacted to form a compressive strength solid structure. Geopolymers are sometimes also referred to in the literature as a subset of alkali-activated materials. In such a material, silica SiO 2 and alumina Al, O 3 are in the central part the so-called in the formation of a geopolymer cement> having a cement-like binder. Geopolymer cement can be utilized in the production of compressive, concrete-like material.
    N It can also be stated that the geopolymer is a cementitious binder which can be utilized for the production of a concrete-like substance E and which is formed from a silicon- and aluminum-containing substance, for example a side-flow material under alkaline conditions. The concrete-like strong material resulting from the reaction of industrial mineral by-products and alkaline constituents N 35 is also commonly referred to as a geopolymer. Alkaline ingredients such as sodium-based solutions are used as reactive substances in the preparation.
    The idea of one embodiment is that the mixer is designed and intended for mixing industrial by-product materials in the manufacture of a geopolymer. The mixer comprises a bucket section for loading and moving the side stream material. The bucket part thus forms a space into which the alloying elements can be loaded and fed. The mixer further comprises mixing equipment for mixing the side stream material loaded into the space bounded by the bucket. The mixer can be connected to a suitable implement using a coupling device. Typically, the implement has a boom to which the agitator can be connected so that it can be moved in a variety of ways by means of boom joints and actuators. The coupling device makes it possible to disconnect the mixer, so that the working machine can be used from time to time for other work tasks, such as for loading the geopolymer crumb presented in this application on the crusher and for loading the crushed material. The mixer can also be removed for maintenance and repairs.
    The idea of one embodiment is that the above-mentioned mixer can be pushed or pushed by means of a working machine to load a pile of material to be processed into the mixer. > In this case, no separate loading equipment is required and the operation is efficient. Furthermore, the solution is advantageous when N the side stream material is in a form which is particularly difficult to handle.
    S 30 The idea of one embodiment is that the mixer E is a bucket-like device in which the volume of the bucket part is at least 1 ml. The volume of the mixer can be 5 - 7 m or S even larger.
    2 The idea of one embodiment is that the bucket part of the mixer is an open structure from above, the mixer being adapted to receive material from the above feed or mixer station. In this case, the mixer can simply be taken below the silo, the dispenser or the feeder. The additional material can thus be fast and efficient when it is made directly in the mixer without intermediate steps and separate equipment.
    The idea of one embodiment is that the mixer can be turned from the mixing position to the emptying position, in which the mass in the mixer is adapted to drain by gravity out of the bucket part. The side-flow materials can form a pasty or pasty mass with each other, as well as with possible additives and water, which is difficult to empty without tipping.
    The idea of one embodiment is that the mixer has a horizontal mixing position and can be turned down relative to the mixing position. The emptying position may be a predetermined downwardly directed angular position. The agitator can be rotated so that its bottom is vertically, and further, in some cases, the agitator can be rotated even beyond the vertical rotation position, i.e. almost upside down. In this way, the emptying of difficult-to-treat pasty masses can be made more efficient. It is also possible to invert or oscillate the mixer during mixing to enhance mixing.
    o The idea of one embodiment is that there is a pivoting device between the agitator and the free end of the implement boom to turn the agitator to the emptying position.
    N The idea of one embodiment is that the mixer S can be turned to the emptying position by articulating the boom E of the implement.
    The idea of one embodiment is that the mixer comprises its own turning device, by means of which the bucket part can be turned with respect to the turning joint from the mixing position to the emptying position.
    The idea of one embodiment is that the agitator equipment of the mixer can be switched on during emptying. This can significantly enhance the mass formed by the difficult-to-treat side stream materials. For example, a pulp consisting mainly of green liquor precipitate may be a pasty or pasty substance which may be difficult or even impossible to empty by pouring or tipping alone.
    The idea of one embodiment is that the mixer comprises at least one vibrating device for enhancing the emptying of the bucket part.
    The idea of one embodiment is that the mixer comprises at least one vibrating device which can be switched on not only during emptying but also during mixing to enhance mixing.
    The idea of one embodiment is that said vibrating device comprises a rotating eccentric body. Alternatively, the vibrator may comprise an impact device.
    The idea of one embodiment is that the mixer comprises at least one measuring device for determining the properties of the material in the mixer. The measurement data of the measuring unit can be transmitted to the dopant station by means of a wireless communication connection, whereby the system can calculate in advance the amount of dopants required in relation to the obtained measurement data. The system can also prepare the additive batches in advance so that the operation S at the alloy station is as smooth as possible and the operation A efficient.
    The idea of one embodiment is that the mixer comprises at least one weighing device for determining the mass of material to be loaded into the bucket part E. Alternatively, the weighing device may be arranged in connection with the implement, for example on a boom or axle system. In this case, real-time information on the weight of the material to be treated and the mass is obtained.
    The idea of one embodiment is that the mixer comprises at least one measuring device for determining the moisture of the material in the mixer. Based on the humidity information, additional humidification can be adjusted in the dopant station if necessary, and further, the humidity information can be used to adjust the amount of other additives.
    The idea of one embodiment is that the mixer comprises at least one measuring device for determining the force required for mixing. The anti-mixing force can be used to determine the properties of the mass to be mixed, such as structure, flexibility, moisture and homogeneity.
    The idea of one embodiment is that the mixer comprises at least one camera for visually evaluating the composition of the pulp. The image data of the camera can be transmitted to the operator of the implement or to the operator or expert in the control room.
    The idea of one embodiment is that the agitator comprises at least one horizontal agitator shaft which can be rotated about its longitudinal axis by means of a rotary motor. A plurality of agitator blades are arranged on the agitator shaft, with agitator surfaces in an angular position with respect to the longitudinal direction of the agitator shaft.
    The idea of one embodiment is that the rotation motor for rotating the agitator shaft is a hydraulic motor. Hydraulic energy is typically well available in the booms of implements. Furthermore, the rotation motor eu and the transmission can be arranged outside the bucket part separately from the materials to be mixed.
    S 30 The idea of one embodiment is that the mixer E comprises two horizontal agitator shafts, o which are rotatable by means of at least one rotary motor S about their longitudinal axes. The directions of rotation 2 of the agitator shafts are opposite to each other and each agitator shaft is provided with a plurality of agitator blades with agitator surfaces in an angular position with respect to the longitudinal direction of the agitator shaft. The agitator blades of the adjacent agitator shafts are arranged axially at different points relative to each other so that the agitator blades of the adjacent agitator shafts partially overlap. Such a biaxial mixer has been found to be particularly effective in mixing sidestream materials. The idea of one embodiment is that the upper surface of the bottom of the bucket part of the mixer is shaped to correspond to the above-mentioned one or two agitator shafts with agitator members. In this case, the base may comprise one or two curved base parts at the agitator shafts. The design of the base can also contribute to the efficiency of the mixing.
    The idea of one embodiment is that the mixer unit comprises a mobile working machine and a mixer connected to its boom. The implement may be a wheel loader. When the agitator is connected to the implement, it is functionally a very flexible mobile unit. If necessary, two or more units can be operated at a factory landfill or similar site, making the system easily scalable.
    The idea of one embodiment is that the agitator is connected to an excavator, forklift, telehandler, tractor or other working machine or S vehicle with a movable platform and> independently moving and controlled. & The idea of one embodiment is that the mixer unit is an independently controlled mobile device. S 30 In some cases, the control of the mixer unit can be arranged by means of an occupied remote control. Furthermore, the operation of the mixer units operating in the work area can be automated, so that they can operate even unmanned. 2 The idea of one embodiment is to mix the fed materials and substances mainly during the transfer of the mixer. In other words,
    mixing takes place during the transfer run from the alloy station and to the discharge site, in which case there is no need for in-situ mixing.
    The idea of one embodiment is that the solution concerns an arrangement in a factory landfill. The arrangement comprises at least one waste stack of the first industrial by-product material. This first side stream material may be the main component of the mixture to be formed. The arrangement further comprises at least one mobile implement equipped with a mixer. The working machine is adapted to take said first industrial by-product material directly with a mixer from said waste heap to the mixer. In this case, no separate device is required for loading. The arrangement also comprises an alloy station with at least a first feed device for feeding second industry side stream material to the material in the mixer of the machine. The mixing device mixes said sidestream materials to form a geopolymer curable mass which, after mixing, is discharged to a casting zone where said sidestream materials continue to react and the resulting material begins to cure. The curing is allowed to take place at least to a partial hardness where the material has a strength suitable for crushing. Emptying can be thought of as casting a paste-like mass in which the mass can be formed into the desired whole. In the arrangement shown, the material to be treated is S in the mixer of the working machine throughout the treatment process from the heap to the casting area. The proposed arrangement is logistically efficient and requires only a very small investment. S 30 The idea of one embodiment is that the arrangement E is without transfer devices outside said working machine between the waste heap and the casting area. S The idea of one embodiment is that a machine equipped with a mixer is a multifunction device adapted to act as a loading, transfer, mixing and casting device between the waste heap and the casting area.
    The idea of one embodiment is that the mixing unit, alloy station and crushing device presented in this document can all be mobile devices that can be easily moved even to different construction sites and factory landfills. It is possible, for example, that the machine chain formed by said devices can, on behalf of the contractor, rotate on different construction sites, whereby the utilization rate of the equipment is very high. The idea of one embodiment is to empty a large number of mass batches formed with a mixer into a uniform curable structure. In other words, the embankments are used as a batch casting of artificial rock or large hardenable piles, boulders or depressions. The casting can be made mold-free on an underground level surface.
    The idea of one embodiment is that the arrangement shown further comprises an extraction device for extracting the hardened mass in the casting area. The material removed by mining, i.e. the quarry, is fed to a crushing device to crush it into crushed material. The crushed material can be transferred from the crusher to the intermediate storage area by means of a conveyor. The transfer and handling of the crushed material is easy compared to the handling of the starting materials and the mass formed by them. The treatment of crushed material does not differ from the treatment of virgin crushed stone and crushed stone.
    o The idea of one embodiment is to allow the geopolymer mass cast at the casting site to harden the teeu into a bedrock and to detach the artificial rock from the artificial rock by means of an extraction device N into the feed opening of the crusher device or into the groove.
    E The idea of one embodiment is to allow the pulp to harden after emptying to a compressive strength of at least 1 MPa before crushing. In this case, the quality of the crushed material is good and the crushing itself takes place smoothly. OF
    The idea of one embodiment is that the mill landfill is in connection with a pulp mill. As a by-product of the pulp mill, a green liquor sludge is generated, which is disposed of as a waste pile at the mill landfill. The first industrial by-product material taken from the waste pile by a mixer is thus a green liquor precipitate, also known as a soda precipitate. The green liquor precipitate is a difficult substance to handle and the solution presented in this document brings a simple solution to its handling.
    The idea of one embodiment is that the first industrial side stream material taken from the waste heap by the mixer is a green liquor precipitate. Green liquor precipitate, or soda precipitate, is a waste that is difficult to handle. With the solution presented, the soda ash is conveyed uniformly by means of a single transfer means to the discharge point or casting area without intermediate emptying and intermediate loading.
    The idea of one embodiment is that the first industrial by-product material is the above-mentioned green liquor precipitate. In this case, the second industrial side stream material fed by the first feed device of the alloy station is blast furnace slag or metakaolin. In experiments, it has been found that these side-flow materials are particularly well suited for each other in the production of a compressive-strength geopolymer. The price of green liquor sludge is negative, ie its safe use makes it possible to avoid waste charges> determined by the Waste Act. Furthermore, the price of said blast furnace slag and metakaolin is advantageous compared to several other side-stream materials. Said materials and N mixtures thereof contain silica and alumina necessary for the reaction of the geopolymer and the curing of S30. E It may also be possible to use a material corresponding to said blast furnace slag o and metakaolin, the element combination of which is similar, with the soda precipitate as a mixture. 2 The idea of one embodiment is that the N 35 alloy station further comprises a third feed device 1
    a feed, i.e. sodium hydroxide (NaOH), to the mixer and further a fourth feeder for feeding the water glass, i.e. sodium silicate Na, SiO 2, to the mixer.
    The idea of one embodiment is that the curable mass mixed in the mixer comprises, as a main ingredient, green liquor precipitate and blast furnace slag, metakaolin or the like. In addition, either lye, water glass or both are mixed into the pulp as an activator. The cured material formed from such materials has been found to have particularly good compressive strength as well as insolubility in experiments.
    The idea of one embodiment is that the dopant station comprises a fifth feed device for supplying water to the mixer to adjust the moisture content of the mass to be mixed.
    The idea of one embodiment is that the solution relates to a method for mixing the pulp. In the method, at least two industrial by-product materials are mixed together in the manufacture of a geopolymer. Mixing is done in a mixer fitted to a mobile implement.
    The idea of one embodiment is that the solution relates to a method in which the mixer is pushed by the machine towards the pile of waste to load the first side stream material into the mixer. After loading, the loaded portion of the first by-pass material in the mixer is transferred from the waste pile to the alloy station. At the alloy position, at least one second sidestream material is added to the first sidestream material N in the mixer. The materials in the mixer S 30 are then mixed with the rotating mixer members of the mixer E. Finally, the mixed mass is transferred to the casting area in the mixer of the working machine and emptied. | S The idea of one embodiment is to empty the mixer by turning its feed opening downwards and at the same time using the mixer members.
    The idea of one embodiment is to weigh the mass of the first side stream material taken from the waste pile by the mixer. In addition, the amount of materials fed at the alloy station is adjusted in response to the determined mass.
    The idea of one embodiment is to determine the moisture of the first side stream material taken into the mixer and to add water to the mixer at the alloy position in response to the determined humidity being below a specified minimum limit.
    The idea of one embodiment is that the solution relates to a method in which several batches of curable geopolymer mass are emptied from the mixer into the casting area in order to form a uniform casting formation. The pulp is allowed to dry for at least two days to give the material a crushable compressive strength. Smaller boulders are then excavated from the cured or partially cured casting and the boulders are crushed in a crusher to a fraction smaller than a predetermined grain size.
    The idea of one embodiment is to allow the material to reach its final hardness in a crushed form. The main hardness of the material is usually reached within about 90 days, but the crushing ability and the strength required for crushing are often reached within a few days of casting. The final hardness is then achieved at the application. When excavation and crushing are performed only on material that has reached its partial hardness, the work is faster to do and does not require as heavy equipment as breaking the fully cured material. In addition, the solution is ecological, as extraction and crushing E require less energy when the material has not yet reached full strength. S The idea of one embodiment is to foam the mass after mixing the admixtures. Foam N 35 makes it possible to produce a light but still strong material. Such a foamed foam with a porous structure can have a good thermal insulation capacity, in which case it can also be used as frost insulation.
    The idea of one embodiment is that the flotation can take place chemically, for example by adding hydrogen peroxide to the pulp, or alternatively mechanically using flotation equipment, which may essentially correspond to equipment for flotation of concrete.
    The idea of one embodiment is that the mixer mixes only one side stream material with the other ingredients to form a geopolymer.
    The idea of one embodiment is to mix three sidestream materials with other ingredients with a mixer to form a geopolymer.
    The above embodiments and the features set forth therein may be combined to provide the desired solutions. BRIEF DESCRIPTION OF THE DRAWINGS Some embodiments of the presented solution are shown in more detail in the following figures, in which Figure 1 shows a schematic and simplified diagram of a geopolymer blend, Figure 2 shows a schematic and simplified diagram of the preparation of a geopolymeric earth Fig. 4 schematically shows a mixing unit formed by a mixer and a working machine, Fig. 5 schematically shows the use of a mixer E 30 at different stages of the geopolymer production process, Fig. 6 shows a front view of a mixer and its rotating mixer shaft, S Fig. 7 shows schematically and a side view of a mixer and its equipment; and Figure 8 is a schematic diagram of the ingredients of the blended mass.
    For the sake of clarity, some embodiments of the presented solutions are shown in simplified form in the figures. In the figures, the same reference numerals are used to refer to the same elements and features.
    DETAILED DESCRIPTION OF SOME EMBODIMENTS Figure 1 shows a geopolymer comprising at least two side-flow materials. In some cases, multiple sidestream materials may be used to form the curable mass. What these sidestream materials and their mixture have in common is that they comprise silica SiO 2 and alumina Al 2 O 3, which react with each other to form a mass that cures to compressive strength. Achievable compressive strength is at least 10 MPa, but is usually greater than 40 MPa, and sometimes even greater than 80 MPa.
    Industrial by-product materials include e.g. enrichment sands, such as the so-called red mud. Further by-product materials are slags from the steel industry, such as blast furnace slag, steel slag and stainless steel slag. Energy industry ashes, such as organic ash from the combustion of wood and inorganic ash from the combustion of coal, burning stone and the like, are also by-product materials. The ashes can be fly ash, grate ash or bottom ash formed in boilers. By-product materials are still generated in the forest industry. Large amounts of green liquor precipitate are formed as waste from the pulp industry.
    = Green liquor sludge is a by-product material formed in the production of pulp in the wood processing industry, which is also called = soda ash. Soda sludge is generated in the sulphate permeation process on the chemical recovery line. The soda precipitate E 30 is removed from the green liquor in a green liquor clarifier before the green liquor is passed to causticization, i.e. for the preparation of cooking chemicals S. The green liquor precipitate is a mixture of various substances insoluble in green liquor, inorganic salts such as oxides, carbonates and sulfides. In addition to the usual alkali metals and calcium and magnesium, it also contains harmful metals. The soda precipitate removed from the process is washed to recover the sodium compounds it contains. The washed soda ash is dried before being dumped in a landfill and has a typical dry matter content of about 50%.
    In addition, one or more activators may be added to the mixture of by-product materials, or in some cases no activator is required but the by-product materials react with each other. Or they may react when water is added to the mixture.
    The method and solutions presented in this document can be used in a variety of ways to make products comprising various industrial by-product materials.
    It is further mentioned that in some cases only one side stream material can be used in the preparation of the geopolymer. In this case, other alloying elements are mixed into the side stream material in a mixer.
    Figure 2 is a schematic diagram of a soil improver manufacturing process described in this application. The steps and features shown in the diagram have been described in detail earlier in this document and will also be apparent from the description of Figure 3.
    In Fig. 3, an industrial plant or factory 1 produces a first side stream material 2, which is disposed of in a factory landfill 3 into a waste pile 4. The waste pile 4 may be a comatose formation, a waste or a pit. It can also be a previously disposed formation. eu The working machine 5 has a mixer 6 with which the side stream N material 2 is taken from the waste heap 4. The mass S 30 of the loaded material and possibly other properties can be measured and the background results are sent to the control unit o CU of the alloy station 7. The combination of the working machine 5 and the mixer 6, i.e. the mixing unit 8, moves to the alloy station 7, where the second side stream material can be fed to the mixer 6 2 from the second feeder 9. The activators can be fed from the third feeder 10 and the fourth feeder 11.
    Furthermore, water can be supplied from the fifth feeder 12 if necessary. The feeding devices 9 to 12 may comprise overhead tanks or silos, below which the mixer 6 can be placed for additional material. In some cases, no other side stream material is fed into the pulp.
    The substances fed to the mixer 6 are mixed during the transfer and the finally formed mass is emptied in the casting zone 13. The mass can be formed into a uniform larger entity, for example a kind of artificial rock 14. The material is allowed to harden to at least partial hardness. Artificial rock 14 can be excavated, for example, with a hydraulic breaker hammer 15, small batch excavation, wedges or some other excavation method. Boulders 16 can be excavated. The detached blocks 16 can be fed into the feed opening of the crusher device 17 and crushed into crushed material 18 having the desired grain size. The crushed material 18 can be temporarily stored 19 and can be transported by road to the place of use.
    The crusher device 17 can be, for example, a jaw crusher, an impact beam crusher or a cone crusher.
    If necessary, excavation and crushing can also be carried out only after a long time, in which case the excavation and crushing equipment is selected according to the situation.
    D Fig. 4 shows a situation in which the working machine 5 pushes N the mixer 6 into the waste heap 4 and thus loads the first side N stream material 2. Fig. 4 illustrates that the S 30 mixer 6 may comprise two horizontal mixer blades 20a, 20b with mixer members and which can o be rotated.
    S Figure 5 shows that the mixer 5 can be 2 turned to the desired position relative to the joint 21 and brought to the N 35 at the alloy station 7 below the feed device 9.
    for feeding. The upper part of the mixer 5 is open to receive the mixers. Furthermore, the mixer 5 can be kept in the desired turning position during mixing. The mixing can take place during the transfer and by the rotating mixer shafts 20a, 20b. Once mixed, the pulp can be foamed before emptying, if desired. The flotation devices can be arranged in connection with the mixer 5. At the emptying point, the agitator 5 can be turned down relative to the joint 21 and the emptying can be further enhanced by means of agitator devices.
    Drainage can be done as a batch casting into a casting pile. In this case, a large number of smaller cartridges 22 form a larger whole.
    It can be seen from Figure 6 that the rotating agitator shaft 20 of the agitator 5 may comprise a large number of arms 23 provided with agitator surfaces 24. The agitator device 26 may have one, two or even more agitator shafts 20 with agitator blades 28 in parallel. Alternatively, the agitator shafts may comprise helical agitator surfaces.
    Figure 7 shows that the agitator shafts 20a, 20b of the agitator device 26 of the agitator 5 can rotate in opposite directions. The rotation motor M for rotating the shafts 20 is located outside the bucket part 27. The mixer 5 further comprises a coupling device 25 for coupling it to the machine. The mixer 5 may also be provided with a sensor S1 D for determining the mass of material in the mixer, N and a sensor 52 for determining the moisture or other property N of the material. The agitator may also include a vibrator T S 30 to provide a vibration that enhances emptying and agitation.
    Fig. 7 further shows a sensor S3 or a corresponding measuring device with which the rotational resistance N 35 caused by the mass to be mixed can be determined by monitoring the motor M. The rotational resistance may manifest as increased rotational
    rotational force, operating energy or the like, or alternatively, for example, a change in the rotational speed. The rotation resistance can be used to obtain information on the flexibility of the pulp and also on the moisture. Furthermore, in connection with the mixer, there may be one or more cameras K, the image information produced by which can be transmitted to the operator in order to make sensory observations of the mass to be mixed. A skilled operator can see the flexibility of the mass from the video camera image.
    Figure 8 shows the possible components of a geopolymer comprising a by-product material of the pulp industry.
    The figures and their description are only intended to illustrate the idea of the invention. However, the scope of the invention is defined in the claims of the application.
